Thevenin and Norton

What is an electronic network?

• A Circuit containing many electrical elements

• Channels on TV

• Lots of wires connected in a computer

• NBC, ABC, CBS, NESN...

Thevenin's Circuit consists of a

• Single voltage source and series resistor

• Single voltage source and parallel resistor

• Current source and series resistor

• Current source and parallel resistor

To find R_TH, you must do this?

• Remove voltage source and place short where the source was removed from.

• Open the voltage source

• Put a short circuit across the voltage source

• Nothing

To find the Thevenin's voltage you must do this to R_L?

• Open R_L

• Add it to the other resistances

• Short it

• Put it in parallel with the other resistances

To find R_TH you always look

• Towards the open circuit

• Away from the open circuit

• Near the open circuit

• It doesn't matter which way you find Rth

Which is R_TH?

• R1

• R2

• Neither

• Both

Find V_TH

• 4.054V

• 5V

• 5.95V

• 10V

What is R_TH?

• 89.2Ω

• 370Ω

• 150Ω

• 220Ω

What is V_TH and R_TH?

• R_TH = 1.5Ω, V_TH = 12V

• R_TH = 6Ω, V_TH = 16V

• R_TH = 18Ω, V_TH = 16V

• R_TH = 8Ω, V_TH = 8V

What is a Norton Circuit?

• One current source and a parallel resistance.

• One current source and a series resistance.

• One voltage source and a series resistance.

• One voltage source and a parallel resistance.
